PAUL A..WAGNER, OF JERSEY QI'IY, NEW JERSEY.

REED roe Looms.

Application filed September 23, 1921, Serial No. 502,641.

T all 10 7mm. it may concern Be it known that 1', PAUL A. Wnevnn, a citizen of the United States, residing at Jersey Jity, in the county of Hudson and State of New Jersey, have invented a certain new and useful Improvement in Reeds for Looms, of which the following is a spec 1 fication.

The OlDJG-L't of theinvention is to provide a reed in wh'ch the dents are accurately,

uniformly and closely spaced, and which may be easily and" economically manufactured.

Another object is to provide means whereby the dent-ends are held in position frictionally in the dent holders during the assembling operation before permanent attachment to such holders and the reed bands, thus facilitating the assembling operation, such means also serving to permit the removal and replacement of worii or defective dents from the finished reed without displacing adjacent dents.

The invention consists in certain novel features of construction by which the above objects are attained, to be hereinafter described and claimed.

The accompanying drawings form a part of this specification and show an approved form of the invention.

Figure 1 is a plan or top view of a por-.

tion of one of the dent holders, on a greatly exaggerated scale.

F igure 2 is a corresponding elevation of the grooved face of such holder.

Figure 3 is a vertical section, taken on the line in Figure 2.

Figure 4; is an elevation on a smaller scale than the preceding figures, showing a lower corner of a reed with certain portions broken away.

Figure 5 is a verticalsection on the line,

55 in Figure 1.

Figure 6 is a horizontal section, taken on the line 66 in Figure 5, and partlyin plan view.

Figure 7 is an edge View of a dent-end, on the same scale as Figures 1, 2 and 3.

Figure 8 is a corresponding face view.

Figure 9 is an elevation of the finished reed, on a still smaller scale.

Similar reference numerals indicate the same parts in all the figures.

Referring to the drawings, 10 is one of a pair of holders each a rectangular bar of steel of suitable dimensions, having equally ing, or an analogous operation,

adapted to receive the dent-ends.

spaced grooves 11 extending transversely across one face, produced by milling, sawslightly wider than the thickness of a dent and The depth of the grooves is preferably the same as the width of the dent. H v

The dents 12 are provided at their ends with means for frictionally engaging. the

walls of the grooves with sufiicient force to prevent displacement by inserted in the holders, of assembling. The means shown comprises spring tongues 13 formed integrally with the dent by suitable dies and offset or bent outwardly on one face of the dent, as in Figures 7 and 8, adapted to be compressed when the dent-end is inserted in its groove and thus yieldingly engage the adjacent wall of the groove, as indicated inFigure 4,

The lands forming the grooves 11 are omitted at each end of each holder 10, to form notches in which the end bars 15 are received, and the bands 16 are applied to the holders and end bars, each band having a flange 17 overlapping the ends of. the dents in their holders, and the thin strips 18, preferably of the same width as the bands are applied to cover the lands and outer edge faces of the dent-ends.

The whole is soldered by dipping or gravity when otherwise and the corners of the reed further during the process the dents and thus increase the stiffness of v the reed, the holders 10 are each slightly bowed outwardly and oppositely as indicated by the dotted lines inFigure 9, and forced into parallelism by suitable means while the dents are introduced and soldered- The effort to re-assume the bowed condition when released induces the desired longitudinal strains on the dents.

To remove a dent, the solder is softened and the strips 18 removed to permit access to the ends of the worn or defective dent which is then removed and replaced by a perfect dent. The strips 18 are then again applied and the whole permitted to cool and harden. The tongues 13 aid in maintaining the adjacent dents in place during the removal and replacement operation.

Other means than the tongues 13 may be employed toinduce frictional engagement of the dent-ends with the grooves of the .holders l0, or the dents maybe simply k3 engagement. p I claim placed in the rooves Wit-houtsu'chfrictional 1.111 a reed, a holder having grooves therein, dent-ends received insaid grooves,

and means formed by ofisetting a portion of each dent-end for .frictionallyengaging such end with the Walls ofits groove. I

2.111 a reed, a holder having grooves therein, dent-ends received in such grooves,

each having grooves formed therein, "and howed outwardly and oppositely, and v a series-ott' dent's secured in such grooves While said holders are forcibly held in parallelism,

whereby said dents arestrained longitudi- .nally when saidholders are released.

etfliIn avreed,.apair ofseparated holders each having equally spaced grooves therein,

a series ofdents havingtheir ends secured in such grooves, end bars received in notches at the ends of said holders, and bands each secured along the plain face of each of said holders and to said end bars, and having a flange overlapping the ends of said dents and -end bars.

- 5. In a reed, a pair of separated holders each having equally spaced, grooves therein,

a series of dents having theirends'sec'ured in such grooves, en'd bar'sreceived in notches at the ends of said holders, bandseach secured along the plain face of eachofsaid holder-sand to said end harsyand having a flange overlapping the ends -of said dents and end bars, and strips each secured to the grooved face of eachof said holders and to said'endbars.
